6 ways the Tesla Powerwall is changing the energy landscape

Some utility firms, eying the growing market share of solar power, are trying to fight back. A few companies have begun charging customers a fee if they have solar equipment installed at their properties. Hitherto, these homeowners have had little choice but to cough up the dough because they needed to rely on the energy company even if they used solar panels. The Powerwall (and similar storage batteries) may make going off the grid completely a realistic option for some homeowners that have sufficient solar capacity, so these suppliers will have to come up with more innovative and fair ways of making money.
